Ariosto Room_Frequency Resolved Acoustic Imaging

Datasel related to the Audio Frequency Acoustic Images of the mural painting Graecia Vetus, Palazzo Chigi of Ariccia The area of analysis (160 cm × 210 cm) covers almost the whole surface of the Graecia Vetus, with 1419 points of measurements at 5 cm distance from one another, at height 1.33 m from the ground. The configurations of the scan unit allowed to cover from height 1.33 m to 3.43 m. The dataset encompasses 4 ABS% matrices (percentage of acoustic energy absorption with respect to the most reflecting point). Specifically, 1 matrix refers to the broadband image (namely IAI - Integrated Acoustic Image) related to the entire frequency band (500 - 12000) Hz, while the remaining 3 matrices refers to narrower frequency band images (namely FRAI - Frequency Resolved Acoustic Image).
